Sorry for asking so much and contributing so little! My Berlingo has developed an odd thing over the past day or so. Basically the idle speed is going up to about 1,400 rpm when in neutral, having just stopped, or is slow to go back down its normal 1,000 rpm idle speed. Probably not explaining it too well - apologies - but I suppose it's like a sticky accelerator cable, except I'm not sure that it is. Any ideas?

Hi all, back to the drawing board. The accelerator cable is moving freely and is not jamming. There are no leaks or holes in the air hoses. In addition, today the van nearly cut out (but didn't) as the revs went down to about 600 rpm. I'm not mechanically minded, but am going towards the ICV as the culprit. What do you reckon? What else could it be apart from the ICV? Thanks as always. Love this forum!
